Arpad Horvath, 75, resided at Meadow Park Long Term Care in London, Ontario. He died on August 31, 2014, the last of Wettlaufer’s alleged victims.

Wettlaufer’s lawyers did not return CNN’s request for comment.

Caressant Care Woodstock Long Term Care Home said it is cooperating with police. Wettlaufer left the home’s employ two and a half years ago, spokesman Lee Griffi said in a statement.

“Our highest priority is to continue to provide for the physical, social and spiritual needs of our residents, and that remains our focus,” Griffi said.

“We deeply regret the additional grief and stress this is imposing on the families involved. We are determined to avoid compromising the police investigation in any way and are therefore unable to provide any additional comment at this time.”
